Abstract
Various embodiments relate to a network node and method thereof including a high stability oscillator and a holdover phase-locked loop ('PLL') wherein the holdover PLL is configured to perform a holdover function by receiving a system clock signal, disciplining the high stability oscillator using the system clock signal to generate a local reference signal, and providing the local reference signal as the system clock signal when the system clock signal becomes unavailable.
